Be it known that 1, Anna. 5'. Foes, of Boston, county of Suifolh, and State of Musso- Pail-Forzning li'iuchines, of which the following description, in connection with the accompanying drawings, is u specification, like letters on the drawings representing like parts.

The present invention relates to u machine for forming pail-bodies and is adopted to be used in the manufacture of pails, boxes, or analogous articles in which the body portion is shaped upon aformer and the bends of the blank from which the body is formed secured together by adhesive material.

It is the object of the invention to facilitote the process of forming the bodies by pro viding the former, upon which. the body is shaped, with combined. wiping and clumping mechanism which draws the body into the proper shape and clamps it, holding the edges together until the adhesive material his set or hardened The machine embodying the invention may advantageously be supplied with u plurality frame, the size and rate of travel of the frame being such that the time elapsing between the insertion of one of the bodies and its removal to be replaced by another is sufficient to per- Init the adhesive material to set. As herein. shown, the said traveling frame cons s rotatable spider having a number of radial members, each provided with a former, so that the several members consecutively come into a position to receive the pail-body, the previously-formed body bein removed and a new blank applied.

. The wiping and clamping mechanism is ranged to beoperuted by a suitable actuating device under-the control of the attendant, the said actuating device being first operated to release the previouslyformed puil body and then actuutedto Wipe up and clamp the new blank.

Figure l is at front elevation of a portion oi. the machine embodying the invention, the said view showing a port of the spider and one of the formers with its wiping :uul eluni 1)- ing mechuniisrn; Fig. a side elevation of Fig. 1; Fig. 3, a front view, on e larger scale, of one of the formers with the wiping and clumping In echonisin open receive the bodyblenk; and. Fig. 4, a plan viev of the some.

she former a is shown conical in shzipe for the formation of the bodies of pails and is surrounded by clamping sudwiping band Z), the ends of which are arranged to be drawn together around the saidv former a after a, blank 23, which. is to form the body of the poll, has been placed upon the said former.-

in the operation of the match inc each blank, one edge of which has been supplied with ads hesive materiel, is inserted endwise between the former a and the band. I), and the said bond is provided with two clumping members b and b", the clamping member 5 being arranged to move in response to the first movement oi the actuating device redially toward the former (1., while the member 11 which is at the othereud of the bout is moved circumferentially zit first and then radially, so as to draw one end of the blank toward the other and then clamp the some upon the other. The blank is inserted so that the part which has received. the adhesive substance lies beyond the clampingnieniber b, the other end being" drown up by the action of the band until it overlies the adhesive substance, after which it is clamped thereon by the member 5)", us best shown in Fig i.

The notueting device 0 is shown is a lever provided at the end with o handle 0 the said lever bein pivot-ally supported upon it stud suitably secured to annrrn c, which so positioned with relation totho orni a which supports the former a, as to bring the connections with the band i) into proper position with relation to said former. ln order to obloin the desired movements of the bond Z) and the clumping members [1' b" the actuator c, which hits operative connections with both ends of the band, is provided with separate connecting members (Z and, c, the member (Z being shown as ulever pivoted couxiolly with the actuator and also having it pivotul eonncction {it b with the member (1 the said member (Z being connected with the hub of the uetuutorv by moons of u springd", through. which the movement of the actuator is inipui-ted to the lover (I. In the first movement of the actuating-lever c towurd the left from the position shown in Fig. 3 the clamping member 11* through the action of the spring iii connection is immediately l'orced into contact with. the blank, near the edge thereof, so as to hold the said blank at one end'iirmly against the surface of the former, the spring permittine; the further movement of the actuating-lever to complete the operation. In such further movement the member 6, which is shown as a link pivotally connected with the clamping member U, is givena considerable nnov 'ement, and the said link c is so arranged that the first part of its movement draws the end of the band (1 which is provided with the clamping"memberl) toward the clamping member 11 the band h thus having a longitudinal movement with relation to the former o and drawing or wiping thebla-nk into position upon the said former until the end thereof overlaps the other end, which is held in position by the member 71.

,The link c is so connected with relation to the acinatm' 1' and the member b that when the said actuator has been moved to its extreme position (shown in Fig. 1) it will impart a radial movement to the member Zr, forcing the same toward the body of the former a and {damping the end of the blank which is under the same over the opposite end of the blank held in position by the member I)". in this final movement oi the aciuatorr t he point where the link 0 is connocted with the act. uat inedever r, is arranged to travel past the center oi. oscillation of the lever r, the temleneybeing, therefore, to hold the member I)" in its clamping position.

in order to provide for the movements described, the link is provided with a yielding" pivotal connection with the actuator c, the said link lazing; shown as directly pivoted at 1" upon the sliding block 1 yieldingl conneeted as by a spring 1; with apart of tnelevar r, so that a radial movement of the piv otal connection (5 with relation to the center oi oscillation of the lever w is provided for.

in orderio facilitate the operai ion of t'orming the pail-bodies, the machine, as shown, can be provided with a number of t'ormers, each having the wiping and damping mechanism above described, and the said l'ormers mounted on a traveling t'rame which may advaniagemxsl) be in the term of a spider, having a hub portionf and spokes or radial members f each of which has secured thereon a former and mechanism, as shown in Figs. 1 and 2. The said frame ma he snitabl driven, as by a spur-gear on a shaft having a driving-pnlleyf, the speed oi rotation being such as to give the operator time to withdraw the formed pail-bodyas a former passes by and substitute therefor a bod vblank, moving; the aetuatingdevi 7 after the insertion thereof to wipe upand clamp the said blank.

The machine is provided with a suiiieient number of formers to give each blank time to dry and set between the time it leaves the point where it is applied and the time it gets back, so that when removed the pail-body is practieall'y finished.

To facilitate the removal. of the pail-body, the former a, which is shown as a metallic shell, is provided with openings or recesses at its opposite edges to give the operator an opportunity to grasp botl sides of the pailbody and pull the same off.

1. The combination with a former for the body-blank of a pail; of wiping-band surrounding the said former and provided at its opposite ends with clamping mcmbers; and means for moving one of the said clamping members radially toward the former and the other clamping member eircumferentially and then radially, substantially as and for the purpose described.

2. The combination with the former; of a wiping and clamping band encircling said former; clamping members at opposite ends of said band; a lever pivotally connected with one of said clamping. members; an actuating lever having a springconnection with said lever to move the same toward the former; and a link connecting said actuating member with the other clamping member whereby the continued movement of said aetnatiim member moves the said clamping member tirst oircumt'erentially and then ,radially with relation to the former, as F forth.

ii. The combination. with a former a a wiping-band provided at opposite end all clamping; members; of a pivotally-sn vied aetuating-lever; a connecting-lever pivoted roaxially with said iuztuating-lwfer and also connected with end of said clamping members; a spring connecting said levers; and a link connected with the other clamping member and having a yielding,- pivotal connection withthe act uaiing' member, substaln tially as described.

l. In a machine for forming pail-bodies, the combination with a plurality of sets of formers, each provided with wipiugand automatiea[iv-clamping mechanism; of a traveling frame for the said formers whereby each former is presented ateertain intervals of time for the removal of a finished body and the insertion of a new blank and. driving mechanism for said frame; as set forth.

In testimony whereof I. have signed my name to this specification in the presence of two subscribing witnesses.
